Hi Fellas, guess that was a bit dumb on my part to ask a question like that due to the modifications, but I do see a lot of these street rodded and just wondered what some were running size wise. Maybe by chance someone would have had one with a newer chassis under it. I appreciate the replies I got. I think I will go with what I am measuring and hope for the best! as far as second or first series, it does have a first series radiator in it. Someone once told me they sort of mixed parts in those years for the GMC. I don't see a way to add pics to a post? thanks
